20'' Hbar Contour, Rifle Gas System, 223 Wylde

The Criterion Barrels 20'' Hbar Contour Rifle Gas System 223 Wylde barrel is purpose-built for shooters who demand precision, reliability, and durability in a modern sporting rifle platform. Manufactured by Criterion Barrels Inc.—a name synonymous with tight tolerances and match-grade performance—this barrel serves law enforcement trainers, competitive shooters, and serious tactical rifle builders who refuse to compromise on accuracy. The 20-inch length strikes the optimal balance between velocity, ergonomics, and practical maneuverability in tactical and 3-gun competition scenarios.

This AR-15 compatible barrel features a heavy contour design that minimizes harmonic vibration and ensures consistent point-of-impact across sustained fire cycles—critical for duty applications and precision work. The 1-in-8 twist rate stabilizes both lighter varmint rounds and heavier tactical loads with equal authority, while the 223 Wylde chamber provides superior headspace control and accepts both 5.56 NATO and 223 Remington ammunition without the pressure spikes associated with tighter 5.56 chambers. At 2.75 pounds, the barrel's weight distribution enhances recoil management without creating excessive muzzle-heavy characteristics, and the .720-inch muzzle diameter with 1/2-28 threading accepts industry-standard suppressors, compensators, and flash hiders without modification.

Professional armorers, range masters, and precision rifle enthusiasts will recognize this barrel as a no-compromise upgrade for duty rifles, training platforms, and competition builds. The rifle-length gas system ensures reliable function across a wide spectrum of ammunition types and suppressor configurations, making it equally at home on a patrol carbine or a precision rifle setup. Installation requires standard AR-15 barrel extension tools and headspace gauging for proper function; once installed, this Criterion barrel will deliver sub-MOA accuracy and thousands of rounds of reliable service.
